How to remove sticky coating from buttons/knobs

[rwlc5]

I have a 2012 Jaguar and all of the buttons and knobs have a sticky/gummy coating. I have not applied any type of dressings. To remove the stickiness I have tried all purpose cleaner, simple green, goof off and isopropyl alcohol. None of those have had any effect. Does anyone have suggestions? Thanks

Here's my first thing to try,

Clean everything with plain tap water a little soap. Like liquid HAND soap you likely already have at a bathroom or kitchen sink.

Go simple - not complex.
